 | versionCode | Version number of the application. The value is a 32-bit non-negative integer less than 2 to the power of 31. It is used only to determine whether a version is later than another version. A larger value indicates a later version. Ensure that a new version of the application uses a value greater than any of its predecessors.  | Number| No|
 | versionName | Version number of the application displayed to users.<br>The value consists of only digits and dots. The four-part format *A.B.C.D* is recommended, wherein:<br>Part 1 (*A*): major version number, which ranges from 0 to 99. A major version consists of major new features or large changes.<br>Part 2 (*B*): minor version number, which ranges from 0 to 99.
